Description

The right drive for the right job. WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback. WD Purple 8TB and higher drives have additional performance headroom to support a new generation of AI-enabled NVRs, video analytics appliances, and deep-learning servers. As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.

    • Does what it’s supposed to. Still doing it.
This bad boy is still trucking along in our security system since purchase. Does what it’s supposed to. Fairly quick remote viewing response, fairly low noise, zero downtime. Work horse.

    • Good stuff
I appreciated being able to purchase these through Amazon at a lower rate than I normally would as a authorized dealer for security cameras. This product in particular is the item of choice for most pros. There is some other items coming out on the market at a lower price, but they have not which did the test of time to this point. And when it comes to security, I don’t like to gamble. Thanks again for the prompt delivery as well. ... show more

    • Great value, a little loud, but overall am happy with it
I actually bought this for my home security camera NVR system, after I advised a friend to buy the exact same thing for their same system and I would install it, as the existing HDD was not large enough for continuous storage beyond several days. It works great, was easy to install, came packaged very well, and the price was very reasonable. The only complaint that I have is that the drive has a very audible "click" to it as it reads and writes, which normally would not be an issue for me or my friend, but we both have the NVR systems in our office, and when it is quiet it can be a little maddening to just hear the clicking of the hard drive. I'm starting to get used to it, otherwise, and do love the fact that it has much more storage capabilities for the application I am using it for. I have not seen any signs of failure, or degradation, and knowing that my HDD as well as the same one for my friend are the same item and have the same noise "issue", it puts my mind at ease thinking it is likely supposed to be that way. This could also just be a common item with surveillance system HDDs, I haven't had anything other than an SSD in quite some time, so maybe I am spoiled! ... show more
